To enter and stay in Serial Programming mode, the AVR microcontroller reset line has to be kept
active (low). Also, to perform a Chip Erase, the Reset has to be pulsed to end the Chip Erase
cycle. To ease the programming task, it is preferred to let the programmer take control of the tar-
get microcontroller reset line to automate this process using a fourth control line (Reset)
